Selain itu, DWDM memberikan fleksibilitas untuk mengangkut berbagai jenis data secara bersamaan dan mengurangi jumlah kabel serat yang diperlukan, membuat instalasi lebih mudah dikelola dan lebih. The DWDM technology accomplishes dynamic usage of bandwidth and low attenuation components of single mode fibers, which uses multiple wavelengths as carriers and concedes them to transmit in the. Dense Wavelength Division Multiplexing (DWDM) is an optical multiplexing technology that can enhance bandwidth over current fibre networks. DWDM task operates by joining and transmitting several signals concurrently at multiple wavelengths on the. Typical DWDM networks of today employ 50-GHz channel spacing, according to the ITU-T G. The Cisco ONS 15216 DWDM System is a suite of passive components used to build and augment dense wavelength division multiplexing (DWDM) networks. DWDM channels are evenly spaced in range from 1260 nm to 1675 nm and categorized in bands and defined by: Original O-Band 1260-1360 nm.
